When I talked to Linksys sales, they said it would do MP3 and WMA, but then said that anything available through VTuner (which these ones are) would be playable, so that didn't make any sense.

If any of you who own the device could see if it will play ASX files, that would be awesome, because that's the only use for the device that I have. If it won't play those, I won't waste my money on the gizmo.
